Sommario/riassunto

This volume, setting out the theory of positive maps as it stands today, reflects the rapid growth in this area of mathematics since it was recognized in the 1990s that these applications of C*-algebras are crucial to the study of entanglement in quantum theory. The author, a leading authority on the subject, sets out numerous results previously unpublished in book form. In addition to outlining the properties and structures of positive linear maps of operator algebras into the bounded operators on a Hilbert space, he guides readers through proofs of the Stinespring theorem and its applications to inequalities for positive maps.  The text examines the maps’ positivity properties, as well as their associated linear functionals together with their density operators. It features special sections on extremal positive maps and Choi matrices. In sum, this is a vital publication that covers a full spectrum of matters relating to positive linear maps, of which a large proportion is relevant and applicable to today’s quantum information theory. The latter sections of the book present the material in finite



dimensions, while the text as a whole appeals to a wider and more general readership by keeping the mathematics as elementary as possible throughout.  .

Sommario/riassunto

Lifelines of Victory, authored by Squadron Leader Murray Harris, is an insightful exploration of the strategic aspects of World War II, focusing on the critical importance of supply lines and logistics in military



operations. The book delves into various battlefronts, including the Libyan Campaign, Abyssinian Campaign, and the Russian Front, analyzing how transportation and supply chains influenced the outcomes of these conflicts. Harris discusses the role of transport officers and the strategic advantage gained through efficient use of fuel lines, sea routes, and land transport. The work emphasizes the complexity of modern warfare and the necessity of maintaining secure lifelines to ensure successful military action. Intended for military historians and strategic studies enthusiasts, the book provides a detailed examination of the logistical challenges faced by the Allied and Axis powers, highlighting the pivotal role of transportation in achieving victory.
